Consider two points in an electric field. The potential at point 1, V1, is 36 V. The potential at point 2, V2, is 196 V. An electron at rest at point 1 is accelerated by the electric field to point 2. Part (a) Write an equation for the change of electric potential energy U of the electron in terms of the symbols given.
Part (b) Find the numerical value of the change of the electric potential energy in electron volts
Part (c) Express v2, the speed of the electron at point 2, in terms of dU, and the mass of the electron me.
Part (d) Find the numerical value of v2 in m/s.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
